Before you replace it in Cornelius
Our published rule applies here exactly as it does in Charlotte, and it is the same rule whoever answers the phone:
- Under 8 years old: we repair it. Elements, thermostats, gas valves and dip tubes are serviceable parts on a tank with years left in it.
- 8 to 12 years old: we repair it if the fix lands under about $500. You are risking $250 to defer $2,000.
- Leaking from the tank body, at any age: replace it. A perforated tank cannot be patched.
What decides which of those you are in is partly the water. Yours comes from Charlotte Water, and that is the supply whose chemistry has been working on the inside of your tank for its whole life. Where the water is soft and lightly buffered it corrodes rather than scales, which means tanks end by anode depletion and perforation rather than a slow decline. A leak from the shell is a genuine end-of-life signal here rather than something to nurse along.

What Cornelius itself changes
The housing in Cornelius
Cornelius is a solid fit for second-cycle water heater work: 24.1% of the stock was built in the 1990s and 32.5% in the 2000s, giving a median build year of 2002. That is a large, consistent cohort of homes whose original units have already been replaced once and whose replacements are now aging out.
The pipe era
Copper and PEX through most of the stock, with polybutylene possible in the earlier 1990s portion. Supply pipework is rarely the cause of hot water complaints here.
